title: Efficient microwave-assisted solid phase coupling of nucleosides, small library generation and mild conditions for release of nucleoside derivatives.
abstract: Nucleosides are essential bio-molecules that participate in a wide array of biological processes involved in maintaining physiologic homeostasis. Recent efforts geared towards the synthesis of nucleoside analogues and development of nucleoside combinatorial libraries using solid phase synthesis has contributed invaluable information towards drug design and development. These studies have provided information concerning the structural requirements of substrate binding pockets of enzymes and evaluation of enzyme kinetics. However, the synthesis of nucleosides and its corresponding analogues remains a challenging and time consuming process. Herein, we report an efficient, microwave assisted solid phase coupling of nucleosides, combinatorial chemistry on the coupled nucleosides to generate small library and mild cleavage conditions to release nucleoside derivatives from its solid support. We anticipate these findings will accelerate the development of synthetic methods or combinatorial library design of nucleoside analogues in similar settings.
